Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of engine components, and particularly relates to an engine oil cooler arrangement system.

BACKGROUND TECHNIQUE

[0002] An oil cooler is a device for accelerating the heat dissipation of lubricating oil to keep it at a lower temperature. In high-performance, high-power enhanced engines, an oil cooler must be installed due to high heat load. The oil cooler is arranged in the lubricating oil circuit, and its working principle is the same as that of a radiator. The current oil cooler usually has an oil cavity, a water cavity and heat dissipation fins to achieve heat exchange. However, the pipeline of such a structure is relatively simple, so the oil and coolant flow away before complete heat exchange during cooling, which not only causes uneven heat exchange, but also increases the power consumption of the engine. As mentioned above, the current oil cooler only functions as a heat exchanger. In the current engine layout, the compactness and integration of the oil cooler component are a difficulty in the current engine design. Therefore, how to make the oil cooler not only achieve the function of heat exchange, but also improve its integration and compactness is a problem to be solved at present.
